摘　　要：描述了一种集群通信中全新的测试解决方案。测试仪器将同时模拟基站和移动电台的通信功能,发送无线集群信令、摩托罗拉车载电台串行外围接口命令和其他测试信息来验证逻辑控制器的性能。其中在测试仪的硬件电路中采用可编程逻辑器件实现串行外围接口通信功能。测试仪软件设计采用模块化设计。在实际使用中发现这种集群逻辑控制器测试仪器通用性好,只需更改处理通信协议的软件模块就可以使测试仪测试基于MPT-137或PAA1382信令的集群逻辑控制器。这种测试仪器在集群通信测试领域应用前景广阔。The paper describes the novel testing project of trunked communication. The testing instrument simulated function of base stations and mobile radios to transmit trunked signaling,command of serial periphery interface of Motorola mobile radios and other information to verify the quality of trunked logic units. The complex programmable logic device accomplished the function of serial periphery interface. And the whole software of the testing instrument was partitioned into different modules ,so this instrument represents good applicability in practical application. By updating the module of communication protocol software, the instrument can check up different trunked logic units based on MPT-1327 protocol,PAA 1382 protocol and so on. The testing instrument has a wide application in the testing field of trunked communication.
